Nintendo reportedly sold about 40,000 Wii U units during the system's first 48 hours of availability in UK.
Industry publication MCV claims that Nintendo has effectively sold out all units across the UK High Street, though it is believed that some are still available.
Nintendo told us last week that it has "strong deliveries of follow-up stock", though MCV claims that "abundant supplies are not expected until the New Year".
CVG understands that the all-important software tie-ratio is in excess of two to one. If true, and taking into account previous suggestions from Nintendo of America exec Reggie Fils-Aime, it means that the Wii U has generally been profitable.
However, no single Wii U game was able to break into the top ten on the UK all-format chart, a disappointment that is new to Nintendo.
Nintendo of America reported 400,000 Wii U sales during the system's first week of availability in the States.
